The recent advancements in quantum computing have sparked concerns about the potential risks to blockchain security. Experts suggest that XRP's architecture may be better equipped to handle these threats than Bitcoin's.
XRP operates on the XRP Ledger, a decentralized, open-source blockchain, which is utilized by Ripple for cross-border transactions. A key difference lies in the exposure of public keys, which can be exploited by a powerful quantum computer using Shor's algorithm to reverse-engineer private keys and drain funds. Typically, public keys are exposed during transactions, but XRP Ledger's audit found that around 300,000 accounts holding 2.4 billion XRP have never sent funds, making them quantum-safe by default. In contrast, Bitcoin's blockchain has a larger portion of vulnerable accounts, with around 6.9 million BTC at risk, equivalent to nearly 35% of its circulating supply.
XRP's key rotation feature and escrow functionality provide additional protection against quantum risks, whereas Bitcoin lacks a key rotation feature, leaving holders more vulnerable. While both cryptocurrencies face theoretical risks, experts believe XRP's design and features make it less exposed to quantum computing threats than Bitcoin.
